ABATTERY INSTALLATION
Install a new battery with (+) side upward.
Battery required for replacement:
Lithium battery CR1216
SECRET CODE REGISTRATION METHOD
Each individual secret code is registered inside
the transmitter, and so it is necessary to register
these codes with the EEPROM inside the receiver
in the following cases.

When either the transmitter or receiver is
replaced;

If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of two different codes can be stored
in the memory area of the EEPROM (two different
transmitters can be used). When the code for the
first transmitter is registered, the previously-regis-
tered codes for two transmitters are cleared.
Therefore, if you are using two transmitters or are
adding a second transmitter, the codes for both
transmitters must be registered at the same time.
Before beginning with the registration, check that
the doors lock normally when the key is used.
1. Connect the MUT-II to the diagnosis connector.
NOTE
This will connect terminal (1) of the diagnosis
connector to earth, and the system will be in
secret code registration standby mode.
Caution
Always turn the ignition switch to OFF before
connecting and disconnecting the MUT-II.
2. Close all the doors.
3. Turn the ignition switch to ACC and then back
to OFF.NOTE
The doors will lock and unlock once at this
time and the system will switch to registration
mode.
4. Press the transmitter switch, and then press
it two times within 10 seconds of the first press.
This will register the code.
5. After registration is completed, the doors will
be automatically locked and unlocked once.
6. If you are using two transmitters or have added
a second transmitter, the same registration
procedure should be carried out for the second
transmitter, and it should be carried out within
one minute after registration of the code for
the first transmitter has been completed. After
the second registration is completed, the doors
will be automatically locked and unlocked once.
7. Registration mode will be cancelled if one of
the following conditions is met.

When the secret codes for two transmitters
have been registered;

When 1 minute has passed after
registration mode started;

If the MUT-II is disconnected (the earth
connection is broken);

If the ignition switch is turned to ON;

If any of the doors are opened;
8. After registration is completed, carry out the
following to check if the keyless entry system
is operable properly.

Remove the ignition key.

Close all the doors.

SRS – SRS Maintenance52B-17
3. Check connector for damage, terminals deformities, and
harness for binds.
4. Check air bag inflator case for dents, cracks or deformities.
5. Check harness and connectors for damage, and terminals
for deformation.
6. Check clock spring connectors and protective tube for
damage, and terminals for deformation.
7. Visually check the clock spring case for damage.
8. Align the mating marks of the clock spring and, after
turning the vehicle’s front wheels to straight-ahead
position, install the clock spring to the column switch.
Mating Mark Alignment
Turn the clock spring clockwise fully, and then turn back
it approx. 3 4/5 turns counterclockwise to align the mating
marks.
Caution
If the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal
operation of the SRS and possibly leading to serious
injury to the vehicle’s driver or front passenger.
9. Install the steering column covers, steering wheel and
the air bag module.
10. Check steering wheel for noise, binds of difficult operation.
11. Check steering wheel for excessive free play.
REPLACE ANY VISUALLY INSPECTED PART IF IT
FAILS THAT INSPECTION. (Refer to P.52B-25.)
Caution
The SRS may not activate if any of the above
components is not installed properly, which could
result in serious injury or death to the vehicle’s driver
or front passenger.

SRS – Post-collision Diagnosis52B-20
REPAIR PROCEDURE
WHEN AIR BAG DEPLOYS IN A COLLISION.
1. Replace the following parts with new ones.

SRS-ECU (Refer to P.52B-24.)

Air bag module (Refer to P.52B-25.)
2. Check the following parts and replace if there are any
malfunctions.

Clock spring (Refer to P.52B-25.)

Steering wheel, steering column and intermediate
joint
(1) Check wiring harness (built into steering wheel)
and connectors for damage, and terminals for
deformation.
(2) Install air bag module to check fit or alignment
with steering wheel.
(3) Check steering wheel for noise, binds or difficult
operation and excessive free play.
3. Check harnesses for binding, connectors for damage,
poor connections, and terminals for deformation.
(Refer to P.52B-18.)
WHEN AIR BAG DOES NOT DEPLOY IN LOW-SPEED
COLLISION.
Check the SRS components. If the SRS components are
showing any visible damage such as dents, cracks, or
deformation, replace them with new ones. Concerning parts
removed for inspection, replacement with new parts and
cautionary points for working, refer to appropriate INDIVIDUAL
COMPONENT SERVICE, P.52B-22.

SRS – Post-collision Diagnosis / Individual Component Service52B-22
Steering wheel, steering column and intermediate joint
1. Check wiring harness (built into steering wheel) and
connectors for damage, and terminals for deformation.
2. Install air bag module to check fit or alignment with steering
wheel.
3. Check steering wheel for noise, binds or difficult operation
and excessive free play.
Harness connector (body wiring harness)
Check harnesses for binding, connectors for damage, poor
connection, and terminals for deformation. (Refer to P.52B-18.)
INDIVIDUAL COMPONENT SERVICE
If the SRS components are to be removed or replaced as a result of maintenance, troubleshooting,
etc., follow each procedure (P.52B-24 – P.52B-31)
Caution
1. SRS components should not be subjected to hear over 93C, so remove the SRS-ECU, air
bag module and clock spring before drying or baking the vehicle after painting.
Recheck SRS system operability after re-installing them.
2. If the SRS components are removed for the purpose of check, sheet metal repair, painting,
etc., they should be stored in a clean, dry place until they are reinstalled.

CHASSIS ELECTRICAL – Ignition Switch and Immobilizer System54-21
ID CODE REGISTRATION METHOD
If using an ignition key that has just been newly purchased,
or if the immobilizer-ECU has been replaced, you will need
to register the ID codes for each ignition key being used
into the immobilizer-ECU. (A maximum of eight different ID
codes can be registered.)
Moreover, when the immobilizer-ECU has been replaced, you
will need to use the MUT-II to register the password that
the user specifies into the immobilizer-ECU. (Refer to the
MUT-II instruction manual for instructions on using the MUT-II.)
Caution
If registering of the ID codes is carried out all
previously-registered codes will be erased. Accordingly,
you should have ready all of the ignition keys that have
already been registered.
1. Connect the MUT-II to the diagnosis connector.
Caution
Turn the ignition switch off before connecting or
disconnecting the MUT-II.
2. Check that the diagnosis code No.54 is not displayed
for MPI system. If the code is displayed, carry out
troubleshooting before proceeding to the next step. (Refer
to GROUP 13A – Troubleshooting).
3. Use the ignition key that is to be registered to turn the
ignition switch to the ON position.
4. Use the MUT-II to register the ID code. If you are
registering two or more codes, use the next key to be
registered to turn the ignition switch to the ON position
without disconnecting the MUT-II.
5. Disconnect the MUT-II. This completes the registration
operation.
6. Check that the engine can be started by each one of
the ignition keys.
7. Check that the diagnosis code No.54 is not displayed
for MPI system. If the code is displayed, erase it. (Refer
to GROUP 13A – Troubleshooting).
